How to run a module with gunicorn?

I have a flask application that I have configured as a python module.

To explain further, this is a simplified structure of my project:

project_dir
  ven
  dir_a
      dir_b
           flask_app
                 __init__.py
                 __main__.py

# __main__.py
.
.
.
app = create_app(...)
client = Client(app)
.
.
.
print("Hello World")
running_app = app.run("0.0.0.0", port=5000)

When I want to run my application, I hit python -m dir_a.dir_b.flask_app

Now I want to run it with gunicorn.

For your reference, this is a sample of running gunicorn

gunicorn -w 1 -b 0.0.0.0:5000 **wsgi:server**

If I want to run the application, from project_dir I run

python -m dir_a.dir_b.flask_app

How should I run my application with gunicorn in my case?

Please note that I want "Hello World" to be printed before running the application

What I have tried:

gunicorn -w 1 -b 0.0.0.0:5000 dir_a.dir_b.flask_app:running_app

I then removed the line running_app = app.run("0.0.0.0", port=5000) and tried

gunicorn -w 1 -b 0.0.0.0:5000 dir_a.dir_b.flask_app:app

and

gunicorn -w 1 -b 0.0.0.0:5000 dir_a.dir_b.flask_app:create_app(...)

None of them worked

You need to tell gunicorn what app to run

The app.run() method is for the development server, so first you’ll have to comment it out or just delete it.

And then

gunicorn -w 1 -b 0.0.0.0:5000 dir_a.dir_b.flask_app:app

Or you could import the app further up in the module.
